TWIN CAM CONVERSION CHAIN DRIVEN CAM 21N

• Allow you to upgrade your 99-06 Twin Cam (except 06 Dyna Glide) to the newer roller-style cam chains and replaces the spring tension cam chain adjusters with the later-style hydraulic adjusters for longer life
• Cam grinds listed are designed to be used with stock lifters; they require the installation of a 07-17 cam plate, oil pump, cam sprockets and chains, and both hydraulic chain adjusters (these parts are not included and must be purchased separately)
• A list of required components is supplied with each set of cams
• Performance should be similar to earlier bikes with the same cam grinds
• Made in the U.S.A.
• 99-06 Twin Cam motors (except 06 Dyna Glide) cannot use the 07-17 cams, as the bearing journal on the earlier motors is .875" in diameter and the 07-17 cams are 1.000" in diameter. The "N" series of cams feature the .875" bearing journal, yet still accept the new style cam support plate
• 99-01 model motors must use the Andrews rear cam sprocket Drag part #0925-0147. 2002-2006 models must use the stock rear cam sprocket, OEM #25728-06
• Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance

Bolt-in cams with more torque at low and middle RPM range (1700-4800 RPM)
Similar to EV23 for heavy bikes
Ideal for heavy bikes with stock compression ratios and stock pistons
Can be used with stock valve springs and tappets
